This phase II trial studies the effect of selinexor when combined with carfilzomib, daratumumab, and dexamethasone in treating patients with high-risk multiple myeloma that has come back (recurrent) or has not responded to treatment (refractory) and who have received 1-3 prior lines of therapy. Selinexor may stop the growth of cancer cells by blocking a protein called CRM1 that is needed for cell growth. Carfilzomib is a type of drug called a proteasome inhibitor. A proteasome is a protein found within cells that has the important role of identifying and marking damaged proteins that are needed to be destroyed by the cell for survival. The inhibition of the proteasome allows for damaged protein to accumulate within cells. This accumulation of damaged protein causes the cell to die. Daratumumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Anti-inflammatory drugs, such as dexamethasone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Giving selinexor in combination with carfilzomib, daratumumab, and dexamethasone may work better than carfilzomib, daratumumab, and dexamethasone alone in treating patients with multiple myeloma.
PRIMARY OBJECTIVE: I. To evaluate the minimal residual disease (MRD) negativity rate, at 10\^-5 level of sensitivity by flow cytometry in bone marrow, with the addition of selinexor to daratumumab, carfilzomib and dexamethasone (SKDd) in patients with high-risk, relapsed or relapsed/refractory multiple myeloma. SECONDARY OBJECTIVES: I. To evaluate the overall response rate (partial response \[PR\] or better) of patients receiving SDKd combination for high risk, relapsed or relapsed/refractory multiple myeloma (MM) and assess depth of response (very good partial response \[VGPR\], complete response \[CR\], stringent complete response \[sCR\]). II. To evaluate the time to response and duration of response in patients receiving SDKd combination for MM. III. To evaluate the progression free survival and overall survival in patient receiving SDKd. IV. To evaluate the MRD negativity rates to the level of sensitivity 10\^-6 by flow cytometry in bone marrow. V. To evaluate the safety profile of the SDKd combination. CORRELATIVE RESEARCH OBJECTIVES: I. To explore the impact of baseline immunomodulatory derivative (IMiD)-14 scores gene expression profile (GEP) on progression free survival. II. Quality of life assessment utilizing Quality of Life Questionnaire (QLQ)-Core (C) 30 and QLQ-Multiple Myeloma (MY) 20 (Cocks et al., 2007; Wisloff et al., 1996). OUTLINE: Patients receive carfilzomib intravenously (IV) over 30 minutes on days 1, 8, and 15 and daratumumab IV as a split dose on cycle 1 days 1 and 2 then on days 8, 15, and 22 of cycle 1, then on days 1, 8, 15, and 22 of cycle 2, days 1 and 15 of cycles 3-6, and day 1 of subsequent cycles. Patients also receive dexamethasone orally (PO) on days 1, 8 15, and 22, and selinexor PO on days 1, 8, and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients without disease progression/clinical relapse or have initiated subsequent anti-cancer therapy, are followed up every 3 months until progression/clinical relapse or initiation of subsequent anti-cancer therapy, and then every 6 months for up to 5 years. Patients with disease progression/clinical relapse or have initiated subsequent anti-cancer therapy are followed up every 6 months for up to 5 years.

Rate of Minimal Residual Disease (MRD) Negative Status
MRD negative status at 10\^-5 level of sensitivity by flow cytometry will be considered synonymous with "success", unless specified otherwise. The proportion of success will be estimated by the number of success divided by the total number of evaluable patients. 95% confidence intervals for the true success proportion will be calculated according to the approach of Duffy and Santner.
Time frame: Up to 5 years post-treatment
Overall Response Rate (ORR)
Will be estimated by the total number of patients who achieve a confirmed response at any time divided by the total number of evaluable patients. A confirmed response is defined as a partial response (PR), very good partial response (VGPR), complete response (CR) or stringent complete response (sCR) noted as the objective status on two consecutive evaluations at least two weeks apart. Exact binomial 95% confidence intervals for the true overall response rate will be calculated. The depth of response (PR versus VGPR versus CR versus sCR) will also be summarized.
Time frame: 2 years
Time to Response
Time to response (TTR) is defined as time from the date of registration to the date of confirmed response using IMWG criteria. TTR will be summarized descriptively (median, range).
Time frame: 2 years
Duration of Response
Duration of response (DOR) is defined as time from date at which the patient's confirmed objective status is noted to the earliest date of progression or death. The DOR will be estimated using the method of Kaplan-Meier.
Time frame: 2 years
Progression-free Survival
The progression free survival (PFS) is defined as the time from registration to the earliest date of documentation of disease progression or death due to any cause. The distribution of PFS will be estimated using method of Kaplan-Meier.
Time frame: 2 years
Overall Survival (OS)
The overall survival (OS) is defined as the time from registration to death due to any cause. The distribution of OS will be estimated using method of Kaplan-Meier.
Time frame: 2 years
MRD Negativity Rate at 10^-6 of Sensitivity
Will be assessed in the bone marrow by flow cytometry estimated as the number of patients who have achieved MRD negative result at 10\^-6 level of sensitivity at any time divided by the total number of evaluable patients. Exact 95% binomial confidence intervals for the true rate of MRD negative response will also be calculated.
Time frame: 2 years
Number of Patients With a Grade 3 or Greater Adverse Event
Will be assessed per National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. The number of patients with at least one grade 3 or greater AE, regardless of attribution, will be reported.
Time frame: 2 years
